Board Game Arena

This game for the color blind will be a problem.
you can not make changes to the colors or when you pass on the cubes or cities with the mouse tell you what color it is?

You could make a suggestion in the bug tracker, using any table as an example:

There is now a preference to change the colors of cubes to become letters.
Also the cities get a tool tip to show the color as text
Also the links are labeled as 'black','red' etc. instead of a train image.

Another preference, just lets you add a tooltip to each city showing it color
